a r t i c l e i n f o a b s t r a c t The design of automatic carrier landing system is a crucial technique for carrier-based aircraft, since it facilitates landing of aircraft on carriers in various severe weather conditions, such as low visibility, heavy wind and rough sea conditions, which can hardly be achieved by manual control. In this paper, a novel method of optimizing the control param...

A study was undertaken at NASA Langley Research Center to establish, demonstrate, and apply methodology for modeling and implementing the aerodynamic effects of MANPADS damage to a transport aircraft into real-time flight simulation, and to demonstrate a preliminary capability of using such a simulation to conduct an assessment of aircraft survivability. Key findings from this study include: su...

Abstract Aircraft Landing Planning is challenging because the inherently limited capacity of airport runways causes bottlenecks. This type planning involves different stakeholders (e.g., airlines, air traffic services providers, authorities, and passengers) faces various uncertainties take-off time variability, or wind speeds). study, conducted in collaboration with European Organization for Sa...

The growth of aviation traffic volume and the attempts to increase operational capacity by reducing aircraft spacing make aviation safety an urgent research issue in the aviation community. Simultaneous runway occupancy of landing aircraft is a precursor of a runway collision, and it is an effective of measure of runway landing safety. This paper presents an analytical method to evaluate the pr...

Managing operations of the aircraft approach process and analyzing runway landing capacity, utilization and related risks require detailed insight into the stochastic characteristics of the process. These characteristics can be represented by probability distributions. The focus of this study is analyzing landings on a runway operating independent of other runways making it as a single runway. ...

Current trends in the design of helicopter have shown that in order to be economically viable and competitive it is necessary to investigate new design concept which may give an improvement in performance and operational flexibility goal and expanding the flight envelope of rotorcraft, but must be shown to be costeffective. The helicopter has carved a niche for itself as an efficient vertical t...

In recent years a clear trend has developed in the aerospace industry towards the procurement of integrated systems from major suppliers (ref. 1). In this process, Messier-Dowty became a provider of integrated landing gear systems who is responsible for supplying a certifiable landing gear system and providing all the system level performance analysis. The aircraft landing gear system retractio...

Trajectory tracking and con guration stabilization for the VTOL aircraft (vertical take o and landing) in the literature has been only considered for the case of slight or zero input coupling. In this paper, our main contribution is to address global con guration stabilization for the VTOL aircraft with a strong input coupling using a smooth static state feedback.

As the demand for the civil aviation has been growing for decades and the system becoming increasingly complex, the use of systems engineering and operations research tools have shown to be of further use in managing this system. In this study, we apply such tools in managing landing operations on runways (as the bottleneck and highly valuable resources of air transportation networks) to handle...
